This cohort study examines ambulatory care revisits and same-day topical antibiotic prescription in insured patients with acute infectious conjunctivitis.

Community-Acquired Pneumonia Diagnosis Following Emergency Department Visits for Respiratory Illness.

Community-acquired pneumonia (CAP) is often considered for children presenting to the emergency department (ED) with respiratory symptoms. It is unclear how often children are diagnosed with CAP following an ED visit for respiratory illness. We performed a retrospective case-control study to evaluate 7-day CAP diagnosis among children 3 months to 18 years discharged from the ED with respiratory illness from 2011 to 2021 and who receive care at 4 hospital-affiliated primary care clinics. Logistic regression was performed to assess for predictors of 7-day CAP diagnosis. Seventy-four (0.7%, 95% confidence interval [CI] = 0.6%, 0.9%) of 10 329 children were diagnosed with CAP within 7 days, and fever at the index visit was associated with increased odds of diagnosis (odds ratio [OR] = 3.32, 95% CI = 1.75-6.28). Community-acquired pneumonia diagnosis after discharge from the ED with respiratory illness is rare, even among children who are febrile at time of initial evaluation.

Pediatric antiarrhythmics and toxicity: A clinical review.

Antiarrhythmic medications are fundamental in the acute and chronic management of pediatric arrhythmias. Particularly in the pediatric patient population, associated antiarrhythmic toxicities represent important potential adverse effects. Emergency medicine clinicians must be skilled in the detection, workup, and management of antiarrhythmic toxicity. This is a clinical review of the indications, pharmacology, adverse effects, and toxicologic treatment of antiarrhythmics commonly used in the pediatric patient population.

Cost of Pediatric Pneumonia Episodes With or Without Chest Radiography.

BACKGROUND AND OBJECTIVES: Despite its routine use, it is unclear whether chest radiograph (CXR) is a cost-effective strategy in the workup of community-acquired pneumonia (CAP) in the pediatric emergency department (ED). We sought to assess the costs of CAP episodes with and without CXR among children discharged from the ED. METHODS: This was a retrospective cohort study within the Healthcare Cost and Utilization Project State ED and Inpatient Databases of children aged 3 months to 18 years with CAP discharged from any EDs in 8 states from 2014 to 2019. We evaluated total 28-day costs after ED discharge, including the index visit and subsequent care. Mixed-effects linear regression models adjusted for patient-level variables and illness severity were performed to evaluate the association between CXR and costs. RESULTS: We evaluated 225c781 children with CAP, and 86.2% had CXR at the index ED visit. Median costs of the 28-day episodes, index ED visits, and subsequent visits were $314 (interquartile range [IQR] 208-497), $288 (IQR 195-433), and $255 (IQR 133-637), respectively. There was a $33 (95% confidence interval [CI] 22-44) savings over 28-days per patient for those who received a CXR compared with no CXR after adjusting for patient-level variables and illness severity. Costs during subsequent visits ($26 savings, 95% CI 16-36) accounted for the majority of the savings as compared with the index ED visit ($6, 95% CI 3-10). CONCLUSIONS: Performance of CXR for CAP diagnosis is associated with lower costs when considering the downstream provision of care among patients who require subsequent health care after initial ED discharge.

Association of Chest Radiography With Outcomes in Pediatric Pneumonia: A Population-Based Study.

OBJECTIVE: Chest radiograph (CXR) is often performed for the evaluation of community-acquired pneumonia (CAP) in the ED setting. We sought to evaluate the association of undergoing CXR with 7-day hospitalization after emergency department (ED) discharge among patients with CAP. METHODS: This was a retrospective cohort study including children 3 months to 17 years discharged from any ED within 8 states from 2014 to 2019. We evaluated the association of CXR performance with 7-day hospitalization at both the patient and ED levels using mixed-effects logistic regression models accounting for markers of illness severity. Secondary outcomes included 7-day ED revisits and 7-day hospitalization with severe CAP. RESULTS: Among 206 694 children with CAP, rates of 7-day ED revisit, hospitalization, and severe CAP were 8.9%, 1.6%, and 0.4%, respectively. After adjusting for illness severity, CXR was associated with fewer 7-day hospitalizations (1.6% vs. 1.7%, adjusted odds ratio: [aOR] 0.82, 95% confidence interval [CI]: 0.73-0.92). CXR performance varied somewhat between EDs (median 91.5%, IQR: 85.3%-95.0%). EDs in the highest quartile had fewer 7-day hospitalizations (1.4% vs 1.9%, aOR: 0.78, 95% CI: 0.65-0.94), ED revisits (8.5% vs 9.4%, aOR: 0.88, 95% CI: 0.80-0.96) and hospitalizations for severe CAP (0.3% vs. 0.5%, aOR: 0.70, 95% CI: 0.51-0.97) as compared to EDs with the lowest quartile of CXR utilization. CONCLUSIONS: Among children discharged from the ED with CAP, performance of CXR was associated with a small but significant reduction in hospitalization within 7 days. CXR may be helpful in the prognostic evaluation of children with CAP discharged from the ED.

Impact of Viral Radiographic Features on Antibiotic Treatment for Pediatric Pneumonia.

BACKGROUND/OBJECTIVES: Chest radiograph (CXR) is routinely performed among children with suspected pneumonia, though it is not clear how specific radiographic findings impact antibiotic treatment for pneumonia. We evaluated the impact of viral radiographic features on antibiotic treatment among children undergoing pneumonia evaluation in the emergency department (ED). METHODS: Children presenting to a pediatric ED who underwent a CXR for pneumonia evaluation were prospectively enrolled. Prior to CXR performance, physicians indicated their level of suspicion for pneumonia. The CXR report was reviewed to assess for the presence of viral features (peribronchial cuffing, perihilar markings, and interstitial infiltrate) as well as radiographic features suggestive of pneumonia (consolidation, infiltrate, and opacity). The relationship between viral radiographic features and antibiotic treatment was assessed based on the level of clinical suspicion for pneumonia prior to CXR. RESULTS: Patients with normal CXRs (n = 400) and viral features alone (n = 370) were managed similarly, with 8.0% and 8.6% of patients receiving antibiotic treatment, respectively (P = .75). Compared with children with radiographic pneumonia (n = 174), patients with concurrent viral features and radiographic pneumonia (n = 177) were treated with antibiotics less frequently (86.2% vs 54.3%, P < .001). Among children with isolated viral features on CXR, antibiotic treatment rates were correlated with pre-CXR level of suspicion for pneumonia. CONCLUSIONS: Among children with suspected pneumonia, the presence of viral features alone on CXR is not associated with increased rates of antibiotic use. Among children with radiographic pneumonia, the addition of viral features on CXR is associated with lower rates of antibiotic use, as compared to children with radiographic pneumonia alone.

Pediatric Intern Clinical Exposure During the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVES: Pediatric health care encounters declined during the coronavirus disease 2019 (COVID-19) pandemic, and pediatric residency programs have adapted trainee schedules to meet the needs of this changing clinical environment. We sought to evaluate the impact of the pandemic on pediatric interns' clinical exposure. METHODS: In this retrospective cohort study, we quantified patient exposure among pediatric interns from a single large pediatric residency program at a freestanding children's hospital. Patient encounters and shifts per pediatric intern in the inpatient and emergency department settings were evaluated during the COVID-19 pandemic, from March to June 2020, as compared with these 3 months in 2019. Patient encounters by diagnosis were also evaluated. RESULTS: The median number of patient encounters per intern per 2-week block declined on the pediatric hospital medicine service (37.5 vs 27.0; P < .001) and intensive care step-down unit (29.0 vs 18.8; P = .004) during the pandemic. No significant difference in emergency department encounters was observed (63.0 vs 40.5; P = .06). The median number of shifts worked per intern per 2-week block also decreased on the pediatric hospital medicine service (10.5 vs 9.5, P < .001). Across all settings, there were more encounters for screening for infectious disease and fewer encounters for respiratory illnesses. CONCLUSIONS: Pediatric interns at the onset of the COVID-19 pandemic were exposed to fewer patients and had reduced clinical schedules. Careful consideration is needed to track and supplement missed clinical experiences during the pandemic.

Declines in the Number of Lumbar Punctures Performed at United States Children's Hospitals, 2009-2019.

OBJECTIVE: To evaluate trends in lumbar puncture (LP) performance among US children's hospitals to assess how these trends may impact pediatric resident trainee exposure to LP. STUDY DESIGN: We quantified LPs for emergency department (ED) and inpatient encounters at 29 US children's hospitals from 2009 to 2019. LP was defined by either a LP procedure code or cerebrospinal fluid culture billing code. Temporal trends and hospital variation in LP were assessed using logistic regression analysis. RESULTS: A total of 215 030 LPs were performed during the study period (0.8% of all encounters). Twenty six thousand and five hundred twenty three and 16 696 LPs were performed in the 2009 and 2018 academic years, respectively (overall 37.1% reduction, per-year OR, 0.935; 95% CI, 0.922-0.948; P < .001), and the rate of LP decreased from 10.9 per 1000 hospital encounters to 6.0 per 1000 hospital encounters over the same period. CONCLUSIONS: LP rates have declined across US children's hospitals over the past decade, potentially resulting in reduced clinical exposure for pediatric resident trainees. Improved procedural simulation during residency may augment the clinical experience.

Trends in Chest Radiographs for Pneumonia in Emergency Departments.

BACKGROUND AND OBJECTIVES: National guidelines recommend against routine use of chest radiography (CXR) for community-acquired pneumonia (CAP) diagnosis in the pediatric emergency department (ED). Given that CXR is often used to exclude the diagnosis of CAP, a reduction in CXR use may result in overdiagnosis of CAP. We sought to evaluate trends in CXR use and assess the association between CXR performance and CAP diagnosis among children discharged from pediatric EDs. METHODS: Children 3 months to 18 years of age discharged from 30 US EDs with (1) CAP or (2) fever or respiratory illness between 2008 and 2018 were included. Temporal trends in CXR use and rates of CAP diagnoses among patients with fever or respiratory illness were assessed. Correlation between hospital-level CXR use and CAP diagnosis rates were evaluated by using Spearman's correlation weighted by hospital volume. RESULTS: CXR usage decreased from 86.6% to 80.4% (P < .001) for patients with CAP and from 30.4% to 18.6% (P < .001) for children with fever or respiratory illness over the 10-year study period. CAP diagnosis rates also declined from 7.8% to 5.9% (P < .001). Hospital-level CXR use was correlated with pneumonia diagnosis rates (correlation coefficient 0.58; P < .001). CONCLUSIONS: Over the past decade, there has been a decline in CXR use in the ED among children with pneumonia and respiratory illnesses, with a decrease in pneumonia diagnoses over the same time period. Future studies are needed to assess the role of CXR in the evaluation of children with possible pneumonia in the ED setting.

Bronchoscopic and histologic findings during lymphatic intervention for plastic bronchitis.

BACKGROUND: Percutaneous lymphatic intervention (PCL) is a promising new therapy for plastic bronchitis (PB). We characterized bronchoalveolar lavage (BAL) and cast morphology in surgically repaired congenital heart disease (CHD) patients with PB during PCL. We quantified respiratory and bronchoscopic characteristics and correlated them with post-intervention respiratory outcomes. METHODS: We retrospectively reviewed patients with PB and surgically repaired CHD undergoing PCL and bronchoscopy at our institution. Pre-intervention characteristics, bronchoscopy notes, BAL cell counts, virology, and cultures were collected. A pathologist blinded to clinical data reviewed cast specimens. Respiratory outcomes were evaluated through standardized telephone questionnaire. RESULTS: Sixty-two patients were included with a median follow-up of 20 months. No patients experienced airway bleeding, obstruction, or prolonged intubation related to bronchoscopy. Of BAL infectious studies, the positive results were 4 (8%) fungal, 6 (11%) bacterial, and 6 (14%) viral. Median BAL count per 100 cells for neutrophils, lymphocytes, and eosinophils were 13, 10, and 0, respectively. Of 23 bronchial casts analyzed, all contained lymphocytes, and 19 (83%) were proteinaceous, with 14 containing neutrophils and/or eosinophils. Median BAL neutrophil count was greater in patients with proteinaceous neutrophilic or eosinophilic casts compared to casts without neutrophils or lymphocytes (P = 0.030). Post-intervention, there was a significant reduction in respiratory medications and support and casting frequency. CONCLUSIONS: The predominance of neutrophilic proteinaceous casts and high percentage of positive BAL infectious studies support short-term fibrinolytic and anti-infective therapies in PB in select patients. Flexible bronchoscopy enables safe assessment of cast burden. PCL effectively treats PB and reduces respiratory therapies.

Pediatric Readmissions After Hospitalizations for Lower Respiratory Infections.

BACKGROUND AND OBJECTIVE: Lower respiratory infections (LRIs) are among the most common reasons for pediatric hospitalization and among the diagnoses with the highest number of readmissions. Characterizing LRI readmissions would help guide efforts to prevent them. We assessed variation in pediatric LRI readmission rates, risk factors for readmission, and readmission diagnoses. METHODS: We analyzed 2008-2009 Medicaid Analytic eXtract data for patients <18 years of age in 26 states. We identified LRI hospitalizations based on a primary diagnosis of bronchiolitis, influenza, or community-acquired pneumonia or a secondary diagnosis of one of these LRIs plus a primary diagnosis of asthma, respiratory failure, or sepsis/bacteremia. Readmission rates were calculated as the proportion of hospitalizations followed by ≥1 unplanned readmission within 30 days. We used logistic regression with fixed effects for patient characteristics and a hospital random intercept to case-mix adjust rates and assess risk factors. RESULTS: Of 150 590 LRI hospitalizations, 8233 (5.5%) were followed by ≥1 readmission. The median adjusted hospital readmission rate was 5.2% (interquartile range: 5.1%-5.4%), and rates varied across hospitals (P < .0001). Infants (patients <1 year of age), boys, and children with chronic conditions were more likely to be readmitted. The most common primary diagnoses on readmission were LRIs (48.2%), asthma (10.0%), fluid/electrolyte disorders (3.4%), respiratory failure (3.3%), and upper respiratory infections (2.7%). CONCLUSIONS: LRI readmissions are common and vary across hospitals. Multiple risk factors are associated with readmission, indicating potential targets for strategies to reduce readmissions. Readmission diagnoses sometimes seem related to the original LRI.

Measuring pediatric hospital readmission rates to drive quality improvement.

The Pediatric Quality Measures Program is developing readmission measures for pediatric use. We sought to describe the importance of readmissions in children and the challenges of developing readmission quality measures. We consider findings and perspectives from research studies and commentaries in the pediatric and adult literature, characterizing arguments for and against using readmission rates as measures of pediatric quality and discussing available evidence and current knowledge gaps. The major topic of debate regarding readmission rates as pediatric quality measures is the relative influence of hospital quality versus other factors within and outside of health systems on readmission risk. The complex causation of readmissions leads to disagreement, particularly when rates are publicly reported or tied to payment, about whether readmissions can be prevented and how to achieve fair comparisons of readmission performance. Despite these controversies, the policy focus on readmissions has motivated widespread efforts by hospitals and outpatient providers to evaluate and reengineer care processes. Many adult studies demonstrate a link between successful initiatives to improve quality and reductions in readmissions. More research is needed on methods to enhance adjustment of readmission rates and on how to prevent pediatric readmissions.
